Structural coloration provides unique features over chemical coloration, such as nonfading, color tunability, and high color brightness, rendering it useful in various optical applications. To develop the structural colors, two different mechanisms of coloration–photonic bandgap (PBG) and surface plasmon resonance (SPR)–have been separately utilized. In this work, a new method is suggested to create structurally colored micropatterns by regioselectively employing SPR in a single film of inverse opal with PBG. The inverse opals are prepared by thermal embedding of opal into a negative photoresist and its subsequent removal. The inverse opals have a hexagonal array of open pores on the surface which serves as a template to make SPR‐active nanostructures through a directional deposition of gold, a perforated gold film and an array of curved gold disks are formed. With a shadow mask lithographically prepared, the gold is regioselectively deposited on the surface of the inverse opal, which results in two distinct regions of gold‐free inverse opal with PBG and gold nanostructure with SPR. As PBG and SPR develop their own structural colors respectively, the resultant micropatterns exhibit pronounced dual colors. More importantly, the micropatterns show the distinguished optical response for evaporation of volatile liquids that occupy the pores.

利用光子带隙和表面等离子体共振设计反蛋白石的多色微图案

结构着色提供了超过化学着色的独特功能，例如不褪色，颜色可调性和高颜色亮度，使其在各种光学应用中很有用。为了形成结构色，已经分别利用了两种不同的着色机理：光子带隙（PBG）和表面等离子体激元共振（SPR）。在这项工作中，提出了一种新的方法，该方法是通过在具有PBG的反蛋白石单膜中区域选择性地使用SPR来创建具有结构颜色的微图案。通过将蛋白石热嵌入到负性光刻胶中并随后将其去除，可以制备反蛋白石。反蛋白石在表面上有六边形的开孔阵列，可作为模板，通过定向沉积金来制造SPR活性纳米结构，形成穿孔的金膜和弯曲的金盘阵列。使用光刻法制备的荫罩，金选择性地沉积在反蛋白石的表面上，这会导致两个不同的无金反蛋白石具有PBG和带有SPR的金纳米结构区域。由于PBG和SPR分别显示其自身的结构色，因此所得的微图案显示出明显的双色。更重要的是，微图案显示出对占据孔的挥发性液体蒸发的杰出光学响应。所得的微图案显示出明显的双色。更重要的是，微图案显示出对占据孔的挥发性液体蒸发的杰出光学响应。所得的微图案显示出明显的双色。更重要的是，微图案显示出对占据孔的挥发性液体蒸发的杰出光学响应。
